brought into Greece by the Aetolians; and in every other country where
they obtained a footing they were brought in by the inhabitants. And the
usual course of affairs is that, as soon as a powerful foreigner enters
a country, all the subject states are drawn to him, moved by the hatred
which they feel against the ruling power. So that in respect to those
subject states he has not to take any trouble to gain them over to
himself, for the whole of them quickly rally to the state which he has
acquired there. He has only to take care that they do not get hold of
too much power and too much authority, and then with his own forces, and
with their goodwill, he can easily keep down the more powerful of them,
so as to remain entirely master in the country. And he who does not
properly manage this business will soon lose what he has acquired, and
whilst he does hold it he will have endless difficulties and troubles.

The Romans, in the countries which they annexed, observed closely these
measures; they sent colonies and maintained friendly relations with(*)
the minor powers, without increasing their strength; they kept down the
greater, and did not allow any strong foreign powers to gain authority.
Greece appears to me sufficient for an example. The Achaeans and
Aetolians were kept friendly by them, the kingdom of Macedonia was
humbled, Antiochus was driven out; yet the merits of the Achaeans and
Aetolians never secured for them permission to increase their power, nor
did the persuasions of Philip ever induce the Romans to be his friends
without first humbling him, nor did the influence of Antiochus make them
agree that he should retain any lordship over the country. Because the
Romans did in these instances what all prudent princes ought to do,
who have to regard not only present troubles, but also future ones, for
which they must prepare with every energy, because, when foreseen, it is
easy to remedy them; but if you wait until they approach, the medicine
is no longer in time because the malady has become incurable; for it
